This book is the sequel to the popular novel, Unwind. Thanks to the events at the end of Unwind, the medical act of unwinding has now come under the light of morality but now unwinding is not a big business that corporations want to see continue. But now, there is a perhaps far more disturbing process called rewinding that involves creating a human purely from unwound parts. With all the main characters from Unwind plus several new ones, there is a journey that questions the meaning life, souls, and what it means to be truly alive.
